# Web API Settings The Web Api service is a http service that can be remotely called to execute a project. The appRules.WebApiService service is normally created by the appRulesSetup exe. If not, you can manually install it running 'As administrator' the related cmd located in the appRulesPortal\Startup\Services Installation folder (install\_webapi\_service.cmd) You can also run appRulesPortal\bin\appRules.WebApiService.exe -i to install (or -u to uninstall) The http address and port of the webapi is indicated in the config file appRules.WebApiService.exe.config in \[Install\_path]\appRules\bin You can also indicate an ApiKey for security purpose, the webapi will launch a project only if the client specifies it in the call. see [Using Web Api](/apprules-r-documentation/platform/platform-features/creating-and-running-projects/running-projects/web-api.md) to learn how to use the webapi. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
